Swollen eyes from a cold should be noted as a result of edema and congestion in the face after a cold, which is caused by poor local blood circulation. Local inflammatory reactions, such as conjunctivitis and blepharitis, can also cause this. Also consider the symptoms of puffy eyes caused by acute glomerulonephritis due to cold. At this time, you should pay attention to local warm compresses, do not drink too much water when sleeping at night, and do not sleep on a pillow that is too high. If necessary, we should also check the blood routine, kidney function, blood complement C3 and C4 levels, as well as blood pressure, urine routine, and even 24-hour urine protein quantification, etc., to clarify the cause and condition according to the test results, and carry out symptomatic treatment.
